Well.known bridge itypegcanries a bilggl 28-WhiCi lt .iis movableatsuhstantially right angles to the direction of travelof the crane bythe provision of tracks 29. The buggy has secured thereto and suspendedtherefrom a 0 frame 30, the lower end of which terminates undersubstantially the center of the buggy. This frame carries a supportingbracket 31 on which is rotatably mounted a pair of supports 32 for theouter end of the conveyor frame 19. The C frame 30 is preferablyprovided with a window or opening 33, as clearly shown in Figure 2, topermit the passage of the conveyor therethrough.

lVith this construction, it will be appar ent that irrespective of thedirection of movement either of the crane 26 or of the buggy 28, thedistance between the bracket 31 and the standard 3 will be varied. Inorder to permit this movement, it is necessary to so mount the conveyorframe 19 that it may slide through the standard 3. This may beaccomplished by providing transversely extending supporting rollers 3ain the standard extending through slots 35 in the conveyor frame 19 andpermitting it to move as required. It will be apparent that at suchtimes the shaft 15 moves endwise through the worm wheel 14 and thedriving means for the sprocket 21, thereby maintaining the desireddriving relationship at all times, irrespective of the position of theconveyor. Movement of the buggy 28 on the tracks 29 is permitted byreason of the rotatable mounting of the standard 3 and of the supports32.

Rotatably carried on the C frame 30 on suitable bearings 36 is aprojector frame 37. This projector frame is preferably so constructedthat with the parts in the position illustrated in Figure 1, the C frameand the projector frafme will be substantially ba l anced with thecenter of gravity on the axis of rotation of the projector frame aboutthe bearings 36. The projector frame itself is also preferably balancedabout its axis of rotation by mounting a driving motor 38 on one end ofthe frame and the projecting apparatus per se on the opposite end of theframe, as will be hereinafter more fully described.

Carried by the frame 37 is a second conveyor '39 adapted to be driven atany desired speed, but preferably at a speed substantially equal to thatof the conveyor 8, by the motor 38 and the intermediate shaft 4-0 withits gear train, as clearly shown in Figure 1. Mounted above the conveyor39 is a hopper a1 adapted to direct the sand from the conveyor 8 toconveyor 39, which in turn discharges into a hopper 4-2. The hopper a2is mounted to discharge directly on to an endless projector 43preferably in the form of a flexible V belt, as clearly shown in Figure3. This projector is supported to travel around suitable guide rollersor pulleys, as well understood in the art, and carries a plurality ofprojecting paddles 44. There are preferably but two of these paddlesprovided, as indicated in Figure 2. The projector is substantiallycompletely enclosed in a suitable housing 45 from the upper portion ofwhich projects a pair of flanges or guides 46, these guides being spaceda distance to permit the travel of the paddles 4e therebetween, but toprevent the material from falling from the projector.

The projector is adapted to be driven at comparatively high speed by themotor 38, which is connected by means of shaft f? and flexible coupling43 with one of the projector driving pulleys. By reason of thisconstruction, it will be understood that the travel of the projectorcauses material supplied by the hopper 42 to gradually pile up ahead ofone of the projector paddles. Due to the high speed of travel of theprojector, this material will be carried to the left hand end of thehousing, as viewed in Figure 2, where it is adapted to be dischargedthrough the outlet 49. As I have before pointed out, this dischargeusually follows a tangential line which is substantially perpendicularto a horizontal plane which includes the axis, or at least one of theaxes, of rotation of the projector. Thus with the projector positionedas in Figure 2, the material will be discharged in substantially thedirection of the dotted line a, which line is substantiallyperpendicular to the dotted line A passing through the axes of rotationof the pulleys which carry the projector. It may happen. however, thatit is desired to fill a mold flask F having substantially the shapeillustrated in this figure. In order to properly compact the sand alongthe sides of the flask, it is necessary to produce a line of dischargeparallel to the chain line Z). To accomplish this, the entire projectormust be so adjusted that the plane containing the axes of the pulleysbefore referred to is brought into substantially the position of thechain line B. This is easily accomplished with the construction hereinprovided, as the projector housing is adapted to be angularly adjustedabout the axis of rotation of the projector driving means. This isaccomplished by providing a segmental gear on one end of the housingmeshing with a spur gear 51 on one end of a shaft 52 journaled insuitable bearings 53 on the frame This shaft is driven by a worm wheel54 meshing with a worm 55 on a shaft 56 carrying at one end a spur gear57. This spur gear in turn meshes with a similar gear 58 on a shaft 59parallel to and overlying a portion of the shaft 56. The shaft 59 at itsopposite end carries a bevel gear 60 adapted to be driven in onedirection by a bevel gear 61 and in the opposite direction by a bevelgear 62. The bevel gears 61 and 62 are loosely mounted on the shaft 47,but

are adapted to .be'operatively; connected :to thisshaftat will-,1through the-medium oila clutch .member. 68.. longitudinally shiftable,
